Patent number: 8050278Abstract: A host computer communicatively linked with a virtual circuit network and communicatively linked with a device over a local area network receives a virtual circuit message from the virtual circuit network, such as an asynchronous transfer mode network. A data structure associating a virtual circuit of the virtual circuit network with the device is referenced, and based on the association, the virtual circuit message is passed to the device over the local area network. The data structure may be a table containing an entry associating the virtual circuit with the device or with the network address of the device.Type: GrantFiled: February 28, 2005Date of Patent: November 1, 2011Assignee: Microsoft CorporationInventors: Mark T. Jeffrey, Mark R. Sestak, Timothy M. Moore

Patent number: 7523172Abstract: A network provides computer services to users and has a centralized data center (CDC) and regional data centers (RDCs) coupled to the CDC. Each RDC is coupled to a plurality of users and maintains for each associated user back up storage. Each user has a user machine with user data stored thereon, and such user data is automatically mirrored to the associated back up storage on the RDC. Each RDC maintains for each associated user a user profile corresponding to the user, and each user and each RDC has a physical location. A user newly couples to the network by contacting the CDC at a network address thereof and receiving from the CDC a network address of an RDC based at least in part on the location of the user. The RDC of the received network address maintains the user profile for the user, and the location of such RDC is expected to be relatively close to the location of the user as compared with the location of all other RDCs.Type: GrantFiled: July 20, 2005Date of Patent: April 21, 2009Assignee: Microsoft CorporationInventors: Joseph H. Mouhanna, Mark T. Jeffrey

Patent number: 6697864Abstract: A login architecture for a computer to access an external network, such as the Internet, through a cable network provides session-based connection to the external computer network. The home computer is first assigned a restricted network address by the cable network. With the restricted network address, the user may access a “walled garden” of the cable network, but cannot access the external computer network. To access the external computer network, a session-based connection, such as a “tunnel” under the Point-to-Point Tunneling Protocol, is formed between the home computer and a connection server of the cable network, and the user is authenticated over the session-based connection. A second network address usable for accessing the external network is then assigned to the home computer.Type: GrantFiled: October 18, 1999Date of Patent: February 24, 2004Assignee: Microsoft CorporationInventors: Ann Demirtjis, Mark T.

Patent number: 5544168Abstract: An ATM telecommunications switch includes a plurality of parallel data switching planes and a parallel control plane, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port. A single data stream is divided between a plurality of input ports and the data is concatenated from a plurality of output ports to reconstitute the data stream. A first rotator connects each input port cyclically to each timelslot of the central switching unit and a second rotator connects each timeslot of the central switching unit cyclically to each output port.Type: GrantFiled: August 17, 1994Date of Patent: August 6, 1996Assignee: GPT LimitedInventors: Mark T. Jeffrey, Thomas S. Maddern, Richard J. Proctor

Patent number: 5528406Abstract: A telecommunications switching device includes a plurality of ports and a plurality of switching units and a connecting circuit for connecting each of the ports to each of the switching units in turn. The connecting circuit includes a photonic channel separation circuit and a photonic space switching circuit.Type: GrantFiled: August 24, 1995Date of Patent: June 18, 1996Assignee: GPT LimitedInventors: Mark T. Jeffrey, Richard J. Proctor, Peter J. Duthie

Patent number: 5459724Abstract: An ATM telecommunications switch includes a plurality of parallel data switching planes and a parallel control plane, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port. Data from a single timeslot on the central switching unit is connected to a plurality of output ports in a point to multipoint operation. A multipoint memory stores information regarding the data addresses and a forward transfer store provides additional storage for multipoint cells.Type: GrantFiled: May 20, 1993Date of Patent: October 17, 1995Assignee: GPT LimitedInventors: Mark T. Jeffrey, Thomas S. Maddern, Richard J. Proctor

Patent number: 5303232Abstract: The invention concerns an Asynchronous Transfer Mode Switch having a plurality of input stages (IS1 . . . 1SN) each for receiving a digital data transmission stream (DS1 . . . 256) consisting of a series of cells and wherein each input stage of the switch includes a circuit (52) for determining the destination of the cells of that data stream, and a circuit (63) for disassembling each cell into cell elements and for allocating to each cell element routing data to enable it to be routed across the central stages.Type: GrantFiled: April 3, 1991Date of Patent: April 12, 1994Assignee: GPT LimitedInventors: Richard J. Proctor, Thomas S. Maddern, Mark T. Jeffrey, Alexander Philip
